I would like to confirm this rule stays: if I purchase long distance add on, it will still roll over until it is used up. I heard the policies have been changed recently. The add on data expires in a month? Thanks in advance for your replies.
I believe all the Black Friday offers open to current customers. You can change the subscription in your account. I believe through website is better than the app on the phone.
I think if you didn't buy roaming package. You don't have option to use your phone plan in US. People receive the notification is because they can access the service.
